Abstract

L'appareil comprenant un objectif zoom (11), un moteur (12), un contacteur de téléobjectif (13) qui est actionné pour faire que le moteur (12) entraîne l'objectif de manière à augmenter sa distance focale, un contacteur de grand angle (14) qui est actionné pour faire que le moteur (12) entraîne l'objectif de manière à diminuer sa distance focale, un moyen de commande est prévu pour modifier la vitesse de changement de plan lorsqu'une condition prédéterminée est remplie pendant l'opération de changement de plan lorsque l'un des contacteurs de téléobjectif (13) ou de grand angle (14) est actionné.The apparatus comprising a zoom lens (11), a motor (12), a telephoto switch (13) which is operated to cause the motor (12) to drive the lens so as to increase its focal length, a switch for wide angle (14) which is operated to cause the motor (12) to drive the lens so as to decrease its focal length, control means is provided for changing the rate of change of plan when a predetermined condition is met during the plan change operation when one of the telephoto (13) or wide angle (14) switches is actuated.
